A fair bit of "bad code" requires at least a passing understanding of the language in question, or the domain involved. But bad comments transcend programming languages. Vilx sends us this one, which comes from code which is definitely running in production.
Oct 20// WARNING!!! Special case for [external API] testing.
// DO NOT LET THIS PIECE OF CODE FIND IT'S WAY TO PRODUCTION
Octavia (previously) didn't just inherit a C# application with dodgy approaches to string handling. It's also an application with questionable understandings of CSS.
CSS is far from perfect, and offers a lot of pitfalls and traps. There's a reason the "impossibility" of vertically centering text is a punchline. It's so flexibly declarative that, in many cases, there are many ways to achieve the same styling result, and it's difficult to pick out the correct one. But one would hope that developers could at least avoid the obviously terrible ones.
"I tried a more complex password and got the same error message, but after trying with a shorter password, it let me through!" wrote Sameer K.
Octavia inherited a decade old pile of C#, and the code quality was pretty much what one would expect from a decade old pile that hadn't seen any real refactoring: nothing but spaghetti. Worse, it also had an "inner platform" problem, as everything they put in their API could conceivably be called by their customers' own "customizations".
One small block caught her eye, as suspicious:
Skill which you don’t use regularly can get rusty. It might not take too much to get the rust off, and remind yourself of what you’re supposed to be doing, but the process of remembering what you’re supposed to do can get a little… damaging.
Lesli spent a big chunk of her career doing IT for an insurance company. They were a conservative company in a conservative industry, which meant they were still rolling out new mainframes in the early 2000s. “Big iron” was the future for insurance.
Long-lived projects can have… interesting little corners. Choices made 13 years ago can stick around, either because they work well enough, or because, well, every change breaks somebody's workflow.
Today's anonymous submitter was poking around the code base of a large, long-lived JavaScript framework. In a file, not modified since 2007, but still included in the product, they found this function.
Time just flies right past, and before you know it, the holidays will be here. Which is why you had better hurry up and try your hand at giving us the best WTF Christmas Story ever, to help us found a new holiday tradition. Or at least, give us one bright spot in the yawning abyss of 2020.
Can you teach us the true meaning of WTFMas?
Alleen started by digging into a PHP method which was just annoying. _find_shipment_by_object_id would, when it couldn't find the ID, return false, instead of the more expected null. Not terrible, but annoying. Worse, it didn't return the shipment eihter, just a key which could be used to fetch a shipment from an array.
Again, all that's just annoying.
"Somehow, a busy day for Blizzard's servers is going to last for around 6 months," writes James G.
Cicely (previously) returned to the codebase which was providing annoyances last time.
This time, the code is meant for constructing objects based on a URL pattern. Specifically, the URL might have a format like api/resource/{id}. Looking at one of the constructors, though, it didn’t want an ID, it wanted an array of them. Cicely wasn’t passing multiple IDs off the URL, and wasn’t clear, from the documentation, how it worked, how you supplied those IDs, or frankly, what they were used for. Digging into the C# code made it clear, but still raised some additional questions.
Marlyn’s employer ships software for a wide variety of CPU architectures. And depending on which branch of the product you were digging into, you might have code that builds for just i386, x86_64, PPC, and PPC64, while another branch might add s390, s390x, and aarch64.
As you might imagine, they have a huge automated test suite, meant to ensure that changes don’t break functionality or compatibility. So it’s a pity that their tests were failing.
Russell F sends us this C# "fuction", and I have to be honest: I have no idea what it's supposed to do. I can trace through the logic, I can see what it does, but I don't understand why it does it.
private List<LaborService> Tranpose(List<LaborService> laborService)
{
int half = (int)Math.Ceiling((decimal)(laborService.Count)/2);
for (int i = 0; i < laborService.Count; i++)
{
if (i < half)
laborService[i].Order = 2 * i;
else
laborService[i].Order = (i - half) + 1;
}
return laborService.OrderBy(x => x.Order).ToList();
}
As a personal perspective, I don't tend to believe that mastery of a programming tool is nearly as important as mastery of the codebase and problem domain you're working on. But there are some developers who just don't want to learn the codebase or what other developers are doing.
Take Jessica's latest co-worker, which is similar to some previous co-workers. In this case, there was a project in flight that was starting to fall behind schedule. Management did what management does in this situation: they threw warm bodies at the project and ensured that it fell further behind.
"Today I learned that the time between 12 PM and 1 PM is "12:28 noon" according to CNN," Drew W. writes.
In .NET, if you want to get the first item from an IList object, you could just use the index: list[0]. You also have a handy-dandy function called First, or even better FirstOrDefault. FirstOrDefault helpfully doesn’t throw an exception if the list is empty (though depending on what’s in the list, it may give you a null).
What I’m saying is that there are plenty of easy, and obvious ways to get the first element of a list.
The holidays are a time of traditions, but traditions do change. For example, classic holiday specials have gone from getting cut down for commercials, to getting snapped up by streaming services. Well, perhaps it's time for a new holiday tradition. A holiday tradition which includes a minor dose of… WTF.
When it comes to backwards compatibility, Microsoft is one of those vendors that really commits to it. It’s not that they won’t make breaking changes once in awhile, but they recognize that they need to be cautious about it, and give customers a long window to transition.
This was true back when Microsoft made it clear that .NET was the future, and that COM was going away. To make the transition easier, they created a COM Interop system which let COM code call .NET code, and vice versa. The idea was that you would never need to rewrite everything from scratch, you could just transition module by module until all the COM code was gone and just .NET remained. This also meant you could freely mix Visual Basic and Visual Basic.Net, which never caused any problems.
Release Notes: October 31, 2019
One of the lines between code that's "not great, but like, it's fine, I guess" and "wow, WTF" is confidence.
For example, Francis Gauthier inherited a WinForms application. One of the form fields in this application was a text box that held a number, and the developers wanted to always display whatever the user entered without leading zeroes.
